Front airbag

1 . A passenger front airbag configured to be mounted in an instrument panel on a passenger side of a vehicle, comprising a front wall and a circumferential wall, wherein the circumferential wall comprises a fixing portion configured to secure the front airbag to the instrument panel in a mounted state of the front airbag so that the front airbag can receive inflation gas directed along a main inlet direction,

wherein the front wall constitutes an impact surface for a vehicle occupant, the front wall having a peripheral edge connected to a first portion of a peripheral edge of the circumferential wall, wherein the length of the front wall peripheral edge is equal to the length of the first portion of the circumferential wall peripheral edge,

wherein the circumferential wall peripheral edge comprises second and third portions that are connected to each other,

wherein the front wall has a centerline that extends longitudinally between a lower end and an upper end of the front wall, the centerline being configured to extend vertically in the vehicle in an inflated condition of the front airbag,

wherein the front wall has a non-mirror-symmetrical portion with respect to the centerline defined by a lateral bulge on one side of the front panel, the front wall having a mirror-symmetrical portion with respect to the centerline below the non-mirror-symmetrical portion, and

wherein the circumferential wall comprises an inflation orifice formed by the fixing portion and through which inflation gas is directed in the main inlet direction, wherein the fixing portion is configured to lie along a fixing plane of the instrument panel in a mounted state of the front airbag, the fixing plane being transverse to an intersecting plane that extends across a center of the inflation orifice in the main inlet direction and intersects the fixing plane along a horizontal line, wherein the front wall and the circumferential wall are configured so that the mirror-symmetrical portion of the front wall is positioned longitudinally below the intersecting plane, facing the inflation orifice, and the mirror-symmetrical portion of the front wall receives the inflation gas flowing into the front airbag in the main inlet direction during deployment so that the forces of the inflation gas act uniformly on the front airbag.

2 . The front airbag recited in claim 1 , wherein the front airbag is configured so that the non-mirror-symmetrical portion of the front wall is positioned longitudinally above the intersecting plane.

3 . The front airbag recited in claim 1 , wherein the front wall and circumferential wall are configured as flat panels.

4 . The front airbag recited in claim 1 , wherein the front wall is formed by one single coherent cut part.

5 . The front airbag recited in claim 1 , wherein the first portion of the peripheral edge of the circumferential wall includes a lateral bulge that is mirror-symmetrical to the lateral bulge of the front wall.

6 . The front airbag recited in claim 1 , wherein the intersecting plane extends to a portion of the front wall directly facing the inflation orifice, wherein the front wall is wider in the bulge than where the- intersecting plane meets the front wall.

7 . The front airbag recited in claim 1 , wherein the front wall and the circumferential wall are configured so that an imaginary line constitutes the shortest distance along the circumferential wall on a first lateral side of the front airbag from the fixing portion to where the intersecting plane meets the front wall, across the front wall along the intersecting plane, and from where the intersecting plane meets the circumferential wall on a second lateral side of the airbag, opposite the first lateral side of the airbag, to the fixing portion.

8 . The front airbag recited in claim 1 , wherein the intersecting plane extends perpendicularly to the fixing plane.

9 . The front airbag recited in claim 1 , wherein the front wall and circumferential wall are configured so that in the mounted state with the front airbag in a deployed condition, along the center line, normal vectors of the front wall are located in a plane that is perpendicular to the fixing plane.

10 . The front airbag recited in claim 1 , wherein the intersecting plane intersects the front wall peripheral edge at two intersections and the length of a distance along the respective side of the circumferential wall from each of the intersections to the fixing portion is substantially equal.

11 . The front airbag recited in claim 1 , wherein the peripheral edge of the circumferential wall is formed by the first, second, and third portions, as well as the fixing portion, and the fixing portion is located between the second and third portions, with the second and third portions being equal in length.

12 . The front airbag recited in claim 1 , wherein the circumferential wall is formed by one coherent cut part.

13 . The front airbag recited in claim 1 , wherein in an inflated state of the front airbag, the lateral bulge of the front wall is on a lateral side of the front airbag that faces a vehicle interior.

14 . The front airbag recited in claim 1 , wherein the first portion of the peripheral edge of the circumferential wall includes a lateral bulge, and wherein the front wall and circumferential wall are configured such that when the front wall and circumferential wall overlie one another in a condition set for being connected together, the lateral bulges substantially extend in opposing directions relative to one another.

15 . The front airbag recited in claim 1 , wherein the front wall and circumferential wall are configured such that when the front wall and circumferential wall overlie one another in the condition set for being connected together, the lateral bulges do not directly overlie one another.
